A patrol unit then spotted the suspect near Fremont Street and Maryland Parkway and arrested him.The victim was transported to a local hospital and expected to be discharged later today, according to Watch Commander Lt.

A significant drop in the number of plastic bags littering Britain's seabeds suggests that a charge on plastic bags and other efforts to tackle marine litter are working, according to a new report.The study, published in the journal Science of the Total Environment, was carried out by scientists at the UK government's Centre for Environment, Fisheries and Aquaculture Science (Cefas), who analyzed data complied between 1992 and 2017 to reveal a drop of nearly 30% in plastic bags on Britain's seabeds.The report inspected 2,461 trawls off the UK's coasts and found that over the 25-year period, 63% of trawls contained at least one plastic litter item. 663

A new study takes a look at how deep the problem of plastics in the ocean goes. Studies have looked at the quantity and spread of plastics in the world’s oceans, and now scientists are getting a better idea of how much of that litter is sinking down to the sea bed.The study, from Australia’s national science agency CSIRO, estimates there is 14 million metric tons of microplastics sitting on the ocean floor. That would be more than 35x as much plastic scientists believe is floating on the surface of the ocean.Microplastics are defined as pieces of plastic that have been worn down by the ocean and other elements into tiny fragments, smaller than 5 millimeters.The team collected samples of deep-sea sediments up to 9,800 feet deep from sites around the Great Australian Bight off the coast of South Australia. The robotic submarine took 51 samples.Scientists found an average of 1.26 microplastic pieces per gram of sediment in the samples.Dr. Denise Hardesty, Principal Research Scientist and co-author of the study, said they were "surprised to observe high microplastic loads in such a remote location.""Our research found that the deep ocean is a sink for microplastics," Hardesty said. "By identifying where and how much microplastic there is, we get a better picture of the extent of the problem."Around 150 million metric tons of plastic are already floating in our oceans -- with an additional eight million tons entering the water each year, according to the World Economic Forum.The researchers say most of the plastic dumped into the ocean likely ends up on the coasts, rather than on the ocean's surface or floor.The samples were taken in the spring of 2017; the study was published in Frontiers in Marine Science on Monday. 1750

A recent study by the U.S. Centers for Disease Control and Prevention found that 6% of more than 3,000 health care workers who were tested had antibodies to coronavirus. Still, after being retested 60 days later, 28% of them had antibody levels so low they were no longer detected."These results suggest that serology testing at a single time point is likely to underestimate the number of persons with previous SARS-CoV-2 infection, and a negative serologic test result might not reliably exclude prior infection," the authors of the study said.According to the CDC, blood samples were taken from 3,248 frontline health care personnel at 13 hospitals between April 3- June 19, 2020.194 of those healthcare workers had detectable antibodies to COVID, the agency said.Participants with higher initial antibody responses were more likely to have antibodies detected at the follow-up test than were those who had a lower initial antibody response, the study concluded.The authors added that the study shows that the window is limited for collecting potentially useful "convalescent plasma" from the blood of patients who have fought off COVID-19. 1151

A pair of children, ages 1 and 3, were shot inside of a car Thursday evening outside the University Of Mississippi Medical Center in Jackson, the Jackson Police Chief told the Clarion-Ledger reported. The shooting briefly prompted fears of an active shooter on the university's campus, causing a heavy police response. The Clarion-Ledger reported that one child was shot in the leg, and the other in the torso. Their conditions have not been publicly released. Following the shooting, a female driver transported the children to the hospital. The suspect was still on the loose as of Thursday evening.  655
